REVISION OF SECTION 614TEST FIBER OPTIC CABLE

Section 614 of the Standard specifications is hereby revised for this project as follows:

Subsection 614.01 shall include the following:

Test fiber optic cable shall include an OTDR on reel test and on all fiber optic cable strands install on the project by the Contractor. In addition, an optical power meter test shall be conducted on fiber strands from all device locations to the regeneration node buildings.

Contractor shall use the Optical Spectrum Analyzer purchased as part of this project to test all course wavelength division multiplexing wavelengths (CWDM). Testing shall be conducted for all CWDM optics at the Colorado Transportation Management Center (CTMC) to individual field Ethernet field Routeres and from the field Routeres to the CTMC. This testing shall commence after all fiber optic cable is tested as stated in this specification.

Bidirectional wavelengths shall be tested at all optics to ensure the proper wavelength is being dropped at the Ethernet Routeres and in turn sent to the CTMC.

As part of the CWDM design all wavelengths will travel on single fibers, and dropped to individual Ethernet Routeres in the field. Tests shall b required at all Router locations to ensure the proper wavelength is delivered and transmitted.

If required, CTMC personnel will aid in this testing.


(r) Test Fiber Optic Cable. For this project this work shall consist of the testing of either multimode or Single Mode fiber optic cable as shown and tabulated in the plans. The testing procedures involve an OTDR test and an Optical Power Meter Test.

Guidelines for fiber optic cable testing include:

(1) Test jumpers and patch cords must be of the same fiber core size and connector type as the cable system:Multimode fiber 62.5/125 mSingle Mode fiber 8.3/125 m

(2) The light source and OTDR must operate within the range of 85030 nm or 130020 nm for multimode testing in accordance with ANSI/EIA/TIA-526-14.

(3) The light source and OTDR must operate with the range of 131010 nm or 155020 nm for Single Mode testing in accordance with ANSI/EIA/TIA-526-7.

(4) The power meter and the light source must be set to the same wavelength during testing.

-2-



(5) The power meter must be calibrated and traceable to the National Institute of Standards and Technology (NIST).

(6) All system connectors, adapters and jumpers must be cleaned as per manufacturer’s instructions before measurements are taken. A) Fiber Optic Cable Testing Equipment. The following is required to perform fiber optic cable tests:(1) An OTDR(2) A test reel, if necessary(3) A light source at the appropriate wavelength(4) Optical Power Measurement Equipment(5) Test Jumpers as specified below

Multimode Fiber TestingCPR Test Jumper-1 shall be 1-5 meters long with connectors compatible with the light source and power meter and have the same fiber construction as the link segment being tested.

B) Optical Fiber Cable Testing with OTDR. The Contractor shall perform an OTDR test of all fibers in all tubes on the reel prior to installation of the fiber. The test results shall be supplied to the Engineer prior to installation of the cable.

If the fiber is specified as “Install Only”, the Contractor shall test the fiber on the reel and provide the test results to the Engineer prior to accepting the cable. After installation, if there are unused portions of cable remaining on the reel, the Engineer may request the Contractor or other qualified technician to perform a reel test. The Contractor shall provide the Engineer the test results prior to delivering the cable to the Engineer. Any cable damaged while in the Contractor’s possession shall be replaced at the Contractor’s expense.

All fiber testing shall be performed on all fibers in the completed end-to-end system. Testing shall consist of a bi-directional end-to-end OTDR trace performed per TIA/EIA-455-61.

OTDR readings will be used to ensure proper installation and to troubleshoot faults. OTDR signature traces will be used for documentation and maintenance. An OTDR provides an indirect estimate of the loss of the cable plant, generally, more accurate or reliable values will be obtained by using an Optical Power Meter. For fibers that are identified in the Plans to be left unterminated, an OTDR shall be used to test end-to-end attenuation.

Loss numbers for the installed link shall be calculated by taking the sum of the bi-directional measurements and dividing that sum by two.

The Contractor shall use an OTDR that is capable of storing traces electronically and shall save each final trace.

To ensure the traces identify the end points of the fiber under test and the fiber designation, the Contractor shall use a test reel, if required, to eliminate the “dead zone” at the start of the trace so that the start of the fiber under test can be identified on the trace. Indicate the length of the test reel for all test results.

If the fiber designation is not indicated on the trace itself, the Contractor shall provide a cross-reference table between the stored trace file name and the fiber designation.

In compliance with EIA/TIA-455-61 “Measurement of Fiber or Cable Attenuation Using an OTDR” the Contractor shall record the following information during the test procedure:

(1) Names of personnel conducting the test.(2) Type of test equipment used (manufacturer, model, serial number, calibration date).(3) Date test is being performed.(4) Optical source wavelength and spectral width.

-4-



(5) Fiber identification.(6) End point locations.(7) Launch conditions (8) Method of calculation for the attenuation or attenuation coefficient.(9) Acceptable link attenuation.

C) Optic Fiber Cable Testing with Optical Power Meter. The Contractor shall conduct an Optical Power Meter Test for each fiber installed.

Multimode segments shall be tested in one direction at both the 850 nm and the 1300 nm wavelength.

Single Mode segments shall be tested in one direction at both the 1310 nm and 1550 nm wavelength.

In compliance with TIA/EIA-526-14A “Optical Power Loss Measurements of Installed Multimode Fiber Cable Plant” and TIA/EIA-526-7 “Measurement of Optical Power Loss of Installed Single-Mode Fiber Cable Plant,” the following information shall be recorded during the test procedure:

(1)Names of personnel conducting the test.(2)Type of test equipment used (manufacturer, model, serial number, calibration date).(3)Date test is being performed.(4)Optical source wavelength, spectral width, and for multimode, the coupled power ratio (CPR). (5)Fiber identification.

(6) End point locations.(7) Test direction.(8) Reference power measurement (when not using a power meter with a Relative Power Measurement Mode). (9) Measured attenuation of the link segment.

(19) Acceptable link attenuation.

The minor attenuation differences due to test direction are on par with the accuracy and repeatability of the test method. Lateral segments within a building are limited to 90 meters. Therefore, attenuation differences caused by wavelength are insignificant, and as a result, single wavelength testing is sufficient.

D) Acceptable Attenuation Values. Acceptable attenuation values shall be calculated for each fiber tested. These values represent the maximum acceptable test values.

1) Multimode Fiber. The general attenuation equation for any multimode link segment is as follows:

Acceptable Link Attn.=Cable Attn.+Connection Attn.+Splice Attn.+CPR Adj.

62.5 m Multi-mode Attenuation Coefficients:

Cable Attn.=Cable Length (km) x (3.40 dB/km@850 nm or 1.00 dB/km@1300 nm)Connection Attn. (ST or SC connectors)=(No. of Connections x 0.39 dB)+0.42 dB.Connection Attn. (LC connectors)=(No. of Connections x 0.14 dB)+0.24 dB.Splice Attn. (Mechanical or Fusion)=Splices x 0.30 dB.

CPR Adj.=See table below.

A connection is defined as the joint made by mating two fibers terminated with re-mateable connectors (e.g. ST, SC, LC).

Multi-mode Light Source CPR AdjustmentCat. 1

The Coupled Power Ratio of a light source is a measure of the modal power distribution launched into a multimode fiber. A light source that launches a higher percentage of its power into the higher order modes of a multimode fiber produces a more over-filled condition and is classified as a lower category than a light source that launches more of its power into just the lower order modes producing an under-filled condition. Under-filled conditions result in lower link attenuation, while over-filled conditions produce higher attenuation. Therefore, adjusting the acceptable link attenuation equation to compensate for a light source’s launch characteristics increases the accuracy of the test procedure.

7) Singlemode Fiber. The general attenuation equation for any Single Mode link segment is as follows:

Acceptable Link Attn. = Cable Attn. + Connector Attn. + Splice Attn.

8.3 m Single-mode Attenuation Coefficients:

Cable Attn.=Cable Length (km) x (0.34 dB/km@1310 nm or 0.25 dB/km@1550 nm)Connection Attn. (ST or SC connectors)=(No. of Connections x 0.39 dB)+0.42 dB.Connection Attn. (LC connectors)=(No. of Connections x 0.14 dB)+0.24 dB.Splice Attn. (Mechanical or Fusion)=Splices x 0.30 dB.

E) Test Procedures. All fiber testing shall be performed on all fibers in the completed end-to-end system.

(1) Multimode Fiber. The multimode fiber cable test shall be conducted as follows:

Clean the test jumper connectors and the test coupling per manufacturer’s instructions.Follow the test equipment manufacturer’s initial adjustment instructions.
